摘要
The present invention relates to a method for generating a sludge dehydration cake by concentrating and dehydrating sludge generated in an immersion membrane filtering unit (100) including a ceramic membrane (201). The method for generating a sludge dehydration cake in a ceramic membrane filtration process comprises the steps of: (a) introducing raw water into an immersion membrane filtering unit (100); (b) performing a membrane filtration treatment for the introduced raw water by a ceramic membrane (201) to generate treated water and sludge; (c) operating a suction filtration pump (401) positioned at a rear end of the immersion membrane filtering unit (100) to collect the treated water generated in the step (b) in a treated water tank (600); (d) operating a sludge inflow pump (190) positioned at the other rear end of the immersion membrane filtering unit (100), and introducing the sludge generated in the step (b) into a sludge pressurization membrane filtering unit (900) including another ceramic membrane (940) to be treated with membrane filtration so as to generate a pressurization membrane-treated water and a dehydration sludge; and (e) generating a sludge dehydration cake by introducing and dehydrating the dehydration sludge into a dehydrator (800).
